Vulnerability from github – Published: 2023-08-04 15:30 – Updated: 2023-12-11 21:30

Details

A heap out-of-bounds memory read flaw was found in the virtual nvme device in QEMU. The QEMU process does not validate an offset provided by the guest before computing a host heap pointer, which is used for copying data back to the guest. Arbitrary heap memory relative to an allocated buffer can be disclosed.

Severity

6.0 (Medium)
